ABSTRACT

A method for authentication of chat bots includes determining that a first chat bot is authenticated, by a server, for first session communication at a first chat session with a first chat application instance. The first chat session is hosted by a first chat service. The method includes determining authentication intent to authenticate, with the server, a second chat bot for a second session communication at a second chat session with a second chat application instance. The second chat session is hosted by a second chat service, where the first chat bot and the second chat bot simulate respective chat application instances. The method also includes providing authentication credentials, via the first chat session, to authenticate the second chat bot with the server for the second session communication.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of U.S. patent application Ser. No. 15/706,238, filed Sep. 15, 2017 and issued Jan. 14, 2020 as U.S. Pat. No. 10,536,452 and is incorporated by reference in its entirety.

BACKGROUND

Embodiments of the inventive subject matter generally relate to the field of communication systems and, more particularly, to communicating in chat sessions using chat bots.

Chat sessions facilitate communication between chat applications in a communication system. A user of a chat application can communicate, over a communication network, with a user of another chat application by transmitting communication to, and receiving communication from, the chat session. A chat bot can simulate a chat application to communicate with other chat applications using the chat session. The user can also have an account at a transaction server. The chat bot can be authenticated to access the user's account at the transaction server. However, authenticating additional chat bots at other chat sessions to access the user's account at the transaction server can be difficult. If access to own user account via other chat sessions is tedious and overly complicated, that may discourage the user from using other chat sessions.

DESCRIPTION OF EMBODIMENT(S)

The description that follows includes exemplary systems, methods, techniques, instruction sequences and computer program products that embody techniques of the present inventive subject matter. However, it is understood that the described embodiments may be practiced without these specific details. For instance, although some examples refer to social media services, other types of media services are contemplated, such as interactive comment sections of online news services or of other online services.

Chat sessions facilitate communication between instances of chat applications running on various devices in a communication system. A user of one instance of a chat application can communicate, over the communication system, with a user of another instance of a chat application by transmitting and receiving communication to/from the chat session. For example, the communication system facilitates the transmission of chat texts, over a communication network, between the instances of the chat applications and the chat session. The chat session, which can be hosted by a chat service, can facilitate communication between the multiple instances of the chat applications. Each chat application, such as a SLACK chat application, or a FACEBOOK MESSENGER application, can be hosted by a user device. The user device can be any type of a personal device such as a mobile phone, tablet, or other computing device.

In some cases, the communication may be between multiple instances of the same type of chat application. In other cases, the communication may involve instances of multiple different types of chat applications. Furthermore, the user can use multiple chat applications on the user device, substantially at the same time. The user device can allow multitasking execution of several applications, each of which can be in a different execution state. An application that is open on the user device is an application that can be in a running state, in a suspended/waiting state, in a blocked state, etc. Thus, the user device can have multiple chat applications open. For example, an instance of the SLACK chat application can be open in a running state on the user device, and an instance of the FACEBOOK MESSENGER chat application can be open in a suspended state on the same user device. One of the chat applications instances can be executing in a web browser on the user device, instead of as a stand-alone application.

Multiple SLACK chat application instances can communicate with each other by transmitting chat texts to, and receiving chat texts from, a SLACK chat session. The chat service can be a part of a social media service. For example, the chat service can be a SLACK chat service that is a part of a SLACK team collaboration tool, or a FACEBOOK MESSEGENGER chat service that is a part of a FACEBOOK social networking service. The chat service itself can be further hosted by a server or another type of a computing device. The user device can thus communicate (via separate chat application instances) with multiple chat sessions, each one being hosted by a different chat service.

A bot application can communicate, via a chat bot, with the chat session and simulate a chat application instance for communicating with the other chat application instances. The chat bot can send and receive chat texts from the chat session. For example, one bot application may simulate a SLACK chat application instance for communicating, using a SLACK chat bot via a SLACK chat session, with other SLACK chat application instances. Another bot application may simulate a FACEBOOK MESSENGER chat application instance for communicating, using a FACEBOOK MESENGER chat bot via a FACEBOOK MESSENGER chat session, with other FACEBOOK MESSENGER chat application instances.

The user may have access to a chat session via a chat application instance. A method for authentication of chat bots includes determining that a first chat bot is authenticated, by a server, for first session communication at a first chat session with a first chat application instance. The first chat session is hosted by a first chat service. The method includes determining authentication intent to authenticate, with the server, a second chat bot for a second session communication at a second chat session with a second chat application instance. The second chat session is hosted by a second chat service, where the first chat bot and the second chat bot simulate respective chat application instances. The method also includes providing authentication credentials, via the first chat session, to authenticate the second chat bot with the server for the second session communication.

In some embodiments, the user can communicate, over a new chat session, with a chat bot (referred to as the new chat bot) that has not yet been authenticated to access the user's account. The bot application that hosts the new chat bot can determine whether the user uses another chat bot, at another chat session, that has been authenticated to access the user's account at the transaction server. Once the bot application determines the authenticated chat bot, the authenticated bot application can provide, via the another chat session, authentication credentials for authentication of the new chat bot. These authentication credentials can be used to authenticate the new chat bot at the new chat session to access the user account at the transaction server.

For frictionless operation, the user has the ability to leverage communication with an authenticated chat bot to authenticate additional chat bot(s) in additional chat sessions. For example, the user can communicate with an authenticated SLACK chat bot to access a user account at the transaction server. The user can also communicate with a new FACEBOOK MESSENGER chat bot, which has not been yet authenticated. The user can use the SLACK chat bot to facilitate authentication of the FACEBOOK MESSENGER chat bot for accessing the user account at the transaction server. The user does not need to separately login and/or provide a password for the FACEBOOK MESSENGER chat bot for use with the transaction server. In some embodiments, the chat application instances on the user device do not need to be placed in a different execution state when performing the authentication. In some embodiments, when performing the authentication, only the two chat application instances are used on the user device, without using additional applications. Providing of additional login and/or password information, or using additional applications can create friction, and also be insecure as the login and/or password information can be accessed by fraudulent entities. The following description, and associated Figures, illustrates various embodiments directed to the ideas listed above.

FIG. 1 is a system diagram 100 illustrating some embodiments of a communication system where chat bots communicate with chat application instances over multiple chat sessions. In an overview of the system diagram 100, a transaction bot application 104 hosts both a transaction chat bot 102(1) and a transaction chat bot 102(2). The bot application 104 communicates using separate chat sessions—via the transaction chat bot 102(1) with a chat session 106(1), and via the transaction chat bot 102(2) with a chat session 106(2). Each of the transaction chat bots 102(1) and 102(2) is associated with a single respective chat session.

The chat sessions 106(1) and 106(2) are hosted by separate chat services 108(1) and 108(2), respectively. For example, the chat service 108(1) can be implemented by SLACK, and the chat service 108(2) can be implemented by FACEBOOK MESSENGER. The chat services 108(1) and 108(2) can be hosted by social media services 110(1) and 110(2), respectively. For example, the FACEBOOK MESSENGER chat service 108(2) can be hosted by FACEBOOK social media service 110(2).

The transaction chat bots 102(1) and 102(2) (also referred to as “chat bots” 102(1) and 102(2)) can each simulate respective chat application instances when communicating, via the chat sessions 106(1) and 106(2), with the chat application instances 112(1) and 112(2), respectively. The chat application instances 112(1) and 112(2) can communicate with other chat application instances (not shown) via the chat session 106(1) and 106(2), respectively. For example, the chat application instance 112(1) can transmit a chat text to the chat session 106(1), where this chat text can be accessed by other chat application instance(s). The chat application instances 112(1) and 112(2) can be hosted by a user device 114.

The user device 114 can also display a user interface (UI) 120. The UI 120 can display visual elements, such as chat texts of the chat sessions 106(1) and 106(2). The UI 120 can also receive input from the user. It is noted that the user device 114 can also receive input from the user via other input elements, such as via a keyboard, mouse, microphone (e.g., from a voice command), among others.

The bot application 104 can interface with a transaction server 116 to provide instructions to the transaction server 116 and receive transaction information regarding users and/or user accounts from the transaction server 116. For example, the transaction server 116 can provide financial services, such as a fund transfer (e.g., a transfer of a certain monetary amount), to users. The transaction server 116 can include transaction accounts, each of which can be associated with a user. The transaction server 116 can facilitate a fund transfer from the user transaction account to a merchant payment account, (i.e., associated with a merchant and in response to instructions received from the transaction bot application 104(1)). The transaction server 116 can be implemented by PAYPAL or another online transaction system that allows users to send, accept, and request fund transfers.

It is noted that although some examples refer to using the transaction server 116, the transaction bot application 104, and the transaction chat bots 102(1) and 102(2) for payment transactions, the transaction server 116 can process general transactions for the user account. For example, the transaction server 116 can be implemented by a Software as a Service (SaaS) server that provides software services for the user device 114 of the user. The chat application instances 112(1) can then be used to access the user account at the SaaS server to provide software services for the user device 114. In some implementations, the transaction server 116 can interface with one or more financial institutions (not shown). The financial institutions can provide financial services to users. The financial institutions 118 can be implemented as banks, credit unions, other deposit-taking institutions that accept and manage deposits and make loans, and other financial service providers. In some embodiments, the financial institutions can include credit card networks, e.g., for funding transfer of money between users.

In one embodiment, the transaction bot application 104 can be implemented as a part of the transaction server 116. The server can be implemented on a single computing device, or on multiple computing devices (e.g., using distributed computing devices or a cloud service). In another embodiment, the transaction bot application 104 is separate from the transaction server 116. The transaction bot application 104 can instantiate the chat bot 102(1), as well as the chat bot 102(2). The transaction bot application 104 can access, via the chat bot 102(1), chat texts that are provided to the chat session 106(1) by the chat application instance 112(1). Similarly, the transaction bot application 104 can access, via the chat bot 102(2), chat texts that are provided to the chat session 106(2) by the chat application instance 112(2). Although FIG. 1 shows a single bot application 104, the transaction server 116 can host several transaction bot applications, e.g., a separate transaction bot application for each of the chat bots 102(1) and 102(2).

A service or an application (such as the transaction bot application 104) can be hosted by a combination of software and hardware. It is noted that the same term “hosting” is used herein to describe both software hosting and hardware hosting. When software hosting, a software service such as the chat service 108, can instantiate and manage multiple chat sessions, such as the chat session 106 and other chat sessions. When hardware hosting, a computing device (such as a server or a user device) can provide resources such as memory, communication, and execution resources for execution of instructions.

The examples presented herein include the chat bot 102(1) being authenticated to access the user account at the transaction server 116. The chat bot 102(2) is initially not authenticated to access the user account at the transaction server 116. The chat sessions 106(1) and 106(2) are hosted by different chat services 108(1) and 108(2). Thus, the authenticated chat bot 102(1) does not have access to the chat session 106(2) at another chat service 108(2). Instead, the chat bot 102(2) needs to be authenticated for accessing the user account based on communication at the chat session 106(2). The authenticated chat bot 102(1) can be used to provide authentication credentials to the chat session 106(1). The authentication credentials can be accessed via the chat application instance 112(1) to authenticate the chat bot 102(2). The authentication of the chat bot 102(2) can be performed by the transaction server 116, or by another server (e.g., an authentication server). For frictionless operation, the user can authenticate multiple chat bots based on authentication credentials received from an authenticated chat bot, where each of the chat bots is hosted by a different chat service.

FIG. 2 is a flow diagram illustrating embodiments of operations for accessing chat session communication for transactions between chat bot applications. The method of FIG. 2 is described with reference to the systems and components described in FIG. 1 (for illustration purposes and not as a limitation). The example operations can be carried out by the transaction bot application 104 and/or by the transaction server 116. It is noted that communication via chat sessions can be accessed (e.g., transmitted and/or received) by the transaction bot application 104 via a respective chat bot from the transaction chat bots 102(1) and 102(2).

Beginning with 202, the bot application determines whether a first chat bot is authenticated, by a server, for first session communication at a first chat session with a first chat application instance. With reference to FIG. 1, the bot application 104 determines whether the chat bot 102(1) is authenticated for session communication at the chat session 106(1) with the chat application instance 112(1). The session communication includes communication that accesses an account, of the user, at the transaction server 116. If the first chat bot is authenticated, the flow proceeds to 206. If the first chat bot is not authenticated, the flow proceeds back to 204.

The bot application 104 can determine authentication of the transaction chat bot 102(1) by communicating with the transaction server 116. The bot application 104 can determine the authentication by accessing a database that stores data entries indicating authentication of transaction chat bots with various chat sessions and/or chat application instances. For example, in some embodiments, the transaction chat bot 102(1) can be authenticated for accessing user accounts of multiple users that communicate using respective chat application instances via the chat session 106(1). Thus, the database can indicate that the transaction chat bot 102(1) can be authenticated for multiple session communications over the chat session 106(1).

At 204, the bot application authenticates, with the server, the first chat bot for first session communication. With reference to FIG. 1, the bot application 104 authenticates, with the transaction server 116, the transaction chat bot 102(1) for first session communication, i.e., for communication accessing an account of the user at the transaction server 116 via the chat session 106(1). The authentication of the first session communication can be configured for a certain duration, and only for communication between the chat bot 102(1) and the chat application instance 112(1) over the chat session 106(1).

At 206, the bot application determines authentication intent to authenticate the second chat bot for second session communication. With reference to FIG. 1, the bot application 104 can determine the authentication intent (for authenticating the chat bot 102(2)) based on chat texts received at the chat session 106(1) and accessed via the chat bot 102(1), or based on chat texts received at the chat session 106(2) and accessed via the chat bot 102(2). FIG. 3 shows one example of a chat text at 300 that can be accessed by the bot application 104 to make this determination. In some embodiments, based on the chat texts, the bot application 104 can also determine whether the chat application instances 112(1) and 112(2) are hosted by the same user device. If the bot application determines the authentication intent, the flow proceeds to 210. If the bot application does not determine the authentication intent, the flow proceeds to 208 and then back to 206. At 208, the bot application continues to communicate with the first chat bot via the first session communication.

At 210, the bot application provides authentication credentials, via the first chat session, to authenticate the second chat bot for the second session communication. With reference to FIG. 1, the bot application 104 can provide, via communication provided by the chat bot 102(1) to the chat session 106(1), the authentication credentials. The authentication credentials can be used by an authenticating server (such as the transaction server 116 or by a stand-alone server) to authenticate the chat bot 102(2) for session communication at the chat session 106(2) with the chat application instance 112(2). Once the chat bot 102(2) is authenticated, the chat application instance 112(2) can provide chat texts (to the chat session 106(2)) that once accessed by the chat bot 102(2) and then processed by the bot application 104, can instruct the bot application 104 to access the user account at the transaction server 116.

In some embodiments, the authentication credentials can be a one-time token for use at the second chat session 106(2). As shown in the example of FIG. 3, the chat bot 102(1) can provide, via the chat text 310, a one-time token at 318. The chat application instance 112(1) can access the one-time token. The one-time token can then be communicated to the chat session 106(2) via the chat application instance 112(2). For example, the one-time token can be automatically copied, at the user device 114, from the chat application instance 112(1) (i.e., as accessed from the chat session 106(1)) to the chat application instance 112(2) (i.e., to be provided to the chat session 106(2)). In one implementation, the user of the user device can copy the one-time token between the different chat application instances. In these examples, either the user device or the user can affect the execution state of the chat application instances 112(1) and 112(2) based on the type of authentication credential that is received.

In some embodiments, the authentication credentials can include a link for authenticating the second session communication. The link can be for accessing an authentication web page at the authentication server. In some embodiments, the link can reference the chat bot 102(2) and/or the chat session 106(2). In some embodiments, the link can be a deep link that is accessed from the chat application instance 112(1) for accessing the chat application instance 112(2) on the user device 114. Once linked to the chat application 112(2), the deep link can be used (e.g., by the user device 114) to generate a new chat text for use by the chat application instance 112(2). The new chat text can be a response (that references the authentication credentials) that, when provided to the chat session 106(2), is accessed by the transaction server (or an authentication server) to authenticate the chat bot 102(2).

In some embodiments, the transaction server 116 can initiate authentication of the chat bot 102(2). The authentication credentials provided by the transaction chat bot 102(1) to the chat session 106(10 can include a prompt for confirmation of the authentication of the chat bot 102(2). The prompt can indicate a request for confirmation of the authentication process (i.e., of authenticating the chat bot 102(2)) via the chat session 106(2). Example of the prompt for authentication is shows at chat text 330.

In some embodiments, the bot application 104 can determine what type of authentication credentials to provide. The authentication credential type selection can be based on a variety of criteria, including on a type of chat sessions being used and/or whether the user device is a mobile device (which can be determined based on the chat texts accessed in the chat session 106(1) and/or 106(2)). For example, the bot application 104 can determine that for the chat session 108(1), a link for authentication is provided. The bot application 104 can determine that the one-time token can be provided only if the user device is a mobile device.

In some embodiments, the bot application 104 can determine which chat bot to use for providing the authentication credentials of 210 (and also for receiving the response of 212). For example, if a third chat bot is also authenticated to access the user account at the transaction server 116, the bot application 104 can determine whether to select the chat bot 102(1) or to use the third chat bot for providing of the authentication credentials. The chat bot selection can be based on a variety of criteria, including whether the user device 114 is a mobile device (which can be determined based on the chat texts accessed in the chat session 106(1) and/or 106(2)). For example, the third chat bot is used when communicating with mobile devices. The chat bot selection can be based on security aspects of the chat session 106(1) versus a third chat session used by the third chat bot, where the chat session 106(1) is determined to provide better security. The chat bot selection can also be affected by the type of authentication credentials being used. In one embodiment, the bot application 104 can determine that multiple chat bots need to be used to authenticate the second chat bot. For example, the bot application can provide the authentication credentials via the chat bot 102(1), but the response at 212 is received via the third chat bot.

At 212, the bot application determines whether it has received a response referencing the authentication credentials. With reference to FIG. 1, the bot application 104 can access, via the chat bot 102(2), chat text(s) at the chat session 106(2) to determine whether a response has been provided that references the authentication credentials. Depending on the type of the authentication credentials, the response will vary. The response can be the one-time token that was initially provided at the chat session 106(1). The response can be authentication received from a web page linked by the link. The response can be a confirmation of the authentication process that was referenced by at the chat session 106(1). Depending on the response, the bot application 104 can determine whether the first chat application instance and the second chat application instance are both hosted by the same user device.

At 214, the bot application authenticates the second chat bot, with the server, for the second session communication. With reference to FIG. 1, the transaction server 116 can authenticate the chat bot 102(2) for communication with the chat application instance 112(1) that accesses the user account. In some embodiments, at 214 the bot application 104 can move a transaction session from the first session communication to the second session communication. The transaction session can be for a transaction between the user account at the transaction server 116 and an account associated with another server. For example, the bot application can move the transaction session from the chat session 106(1) to the chat session 106(2).

FIG. 3 illustrates embodiments of communication, via chat sessions, for authentication of the additional chat bot. Chat text 300 illustrates a chat text that can be provided, by the chat application instance 112(1), to the chat session 106. The chat text 300 can be accessed, via the chat bot 102(1), from the chat session 106. The chat text 300 includes chat text portions (also referred to as “portions”) 302-308. The bot application 104 can access, via the chat bot 102(1), the chat text 300 and parse the various portions 302-306, such as to determine whether the chat text 300 indicates authentication intent. The portion 302 of “user:” indicates that the chat application instance 112(1) is transmitting the chat text 300. The portion of “Bot” 304 indicates that the chat text 300 is addressed to the chat bot 102(1). The portion 306 of “I would like to authenticate with SLACK bot” indicates authentication intent by the user of the chat application instance 112 for authenticating the chat bot 102(2).

The chat text 310 can include portions 312-319. As indicated by 312, the bot application 104(1) can transmit, via the chat bot 102(1) (named “PayPal Bot 1” in this example), the chat text 310 to the chat session 106(1). The chat text 310 includes examples of authentication credentials. In the depicted example, the portion 314 of “user” indicates that chat text 310 is addressed to the user. The portion of 316 indicates that the token is presented at 318. However, the portions 318 and 319 are provided as an example only, and may vary based on a type of authentication credentials being provided at the chat text 310. For example, the portion of 319 is a link that can be provided instead of the token at 318.

The chat text 320 can include portions 322-328. The chat text 320 is provided via the chat session 106(2). The portion 322 of “user:” indicates that the chat application instance 112(2) is transmitting the chat text 320 (as it is addressed to the chat bot 102(2) as indicated by 324). The chat text 326 indicates that the token is provided at 328. The chat text 320 is an example of a response that references the authentication credentials. In other embodiments, a different response can be provided using the chat text 320 or via other methods, such as by confirmation of the authentication and/or by accessing a link.

The chat text 330 can include portions 332-336. As indicated by 332, the bot application 104 can transmit, via the chat bot 102(2), the chat text 330 to the chat session 106(2). The portion of 336 is a prompt for the user (as indicated by 334) to confirm the authentication of the chat bot 102(2). It is noted that in some embodiments, the chat text 330 can instead be transmitted to the chat session 106(1) by the chat bot 102(1). The chat text 330 is a prompt for the response that references the authentication credentials.

FIG. 4 is a timing diagram illustrating one embodiment of authentication of the additional chat bot at the additional chat session. As shown by FIG. 4, the chat application instance 112(1) and the chat bot 102(1) communicate with each other using a chat session 106(1). FIG. 4 indicates that the chat bot 102(1) is already authenticated with the transaction server. FIG. 4 indicates that the chat bot 102(2) is new, meaning that it is not yet authenticated with the transaction server. The communications of FIG. 4 can be performed over one or more communication networks. Portions of the timing diagram of FIG. 4 can correspond to the flow diagram of FIG. 2 and/or to the communication shown in FIG. 3. It is noted that not all of the communication between the chat bots and the chat application instances are shown. Furthermore, some of the communication shown is optional.

At 402, the chat application instance 112(2) can provide a chat text at the chat session 106(2). At 404, the chat bot 102(2) can access the chat text (provided at 402) at the chat session 106(2). At 408, the authentication server (e.g., the transaction server 116) can determine an intent to authenticate the chat bot 102(2), based on the chat text accessed at 404. At 410, the chat bot 102(2) can provide a chat text to the chat session 106(2) requesting an indication of whether the user is using another chat bot that is authenticated for accessing the user account. Since the transaction chat bot 102(2) is not yet authenticated, the transaction server may not have a record (e.g., a data entry in a database) indicating whether the user can access the user account using another chat bot (e.g., such as the chat bot 102(1)).

At 412, the chat application instance 112(2) can provide a chat text, to the chat session 106(2), indicating that the user uses the chat bot 102(1) for authenticated access to the user's account at the transaction server. In some embodiments, the chat text at 412 is provided automatically, e.g., by the chat application instance 112(2) in response to the chat text at 410. At 413, the chat bot 102(2) can access the chat text indicating the authenticated chat bot 102(1). At 414, the transaction server can determine (e.g., by accessing the database) that the authentication intent is to authenticate the chat bot 102(2) for the same user account that the chat bot 102(1) is already authenticated. In some embodiments, each of the chat bots 102(1) and 102(2) is an instance of a chat bot, and each chat bot instance is communicating via only one chat session at a time.
